Abstract: The cassette tape recorder for the four common types of cassettes according to German Industrial Standards DIN 32 715 T, 32 715 W, and the so-called micro-cassette as well as the mini-M-cassette comprises three sound head carriers (10, 20, 30) adapted to be moved selectively into operating position. Furthermore, the spacing between winding shafts (2,2') is adjustable by a movable cam disc (17). This adjustment is taken care of by cam disc engaging fixtures (23, 33) at the movable sound head carriers (20 and 30, respectively) and by a spring (18) holding the cam disc (17) in an inoperative position against a stop. Likewise provided are adjustable winding heads (3,3') causing different engagement members (4,6) to become effective for the winding drive, the adjustment of the winding heads (3,3') also being effected upon moving of the sound head carriers (10,20,30).

Abstract: The specification describes a magnetic tape cartridge, more particularly a miniature one, with access openings arranged in one narrow side of the cartridge housing for the magnetic heads. The magnetic tape is supported in the access openings on resilient cushions. In the direction of tape travel upstream and downstream and between the access openings guide pins, fixed to the cartridge housing, are provided for the magnetic tape. The cushions are arranged on the arms of a double lever of resiliently elastic material, which is held by joint lugs and a pin in two plan-parallel flat strips fixed to the cartridge so as to allow pivoting movement. The strips extend perpendicularly and fit immediately underneath the narrow side having the access openings and the strips are fixedly connected together by the guide pins with a spacing between the strips.
